pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.

我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。

RT/V this expression becomes Cv dT over T is equal to CvdT/T=-RdV/V minus R dV over V.

这样，or，RT，over，V，bar。，So，now，这个等式就,可以化成。
